Two systems of equations are shown. Which TWO of the following statements each provide sufficient reasoning to show that the systems have the same solution?

A The two equations in the second system are multiples of the two equations in the first system.

B The two constant terms in the second system are multiples of the two equations in the first system.

C The graphs of the equations in the first system coincide with the graphs of the equations in the second system.

D The slopes of the graphs of the equations in the first system are equivalent to the slopes of the graphs of the equations in the second system.

E The x -intercepts of the graphs of the equations in the first system coincide with the x -intercepts of the graphs of the equations in the second system.

How many days was the temperature above 90 degrees?

Part one: measurements 1. measure your own height and arm span (from finger-tip to finger-tip) in inches. you will likely need some from a parent, guardian, or sibling to get accurate measurements. record your measurements on the "data record" document. use the "data record" to you complete part two of this project. name relationship to student x height in inches y arm span in inches archie dad 72 72 ginelle mom 65 66 sarah sister 64 65 meleah sister 66 3/4 67 rachel sister 53 1/2 53 emily auntie 66 1/2 66 hannah myself 66 1/2 69 part two: representation of data with plots 1. using graphing software of your choice, create a scatter plot of your data. predict the line of best fit, and sketch it on your graph. part three: the line of best fit include your scatter plot and the answers to the following questions in your word processing document 1. 1. which variable did you plot on the x-axis, and which variable did you plot on the y-axis? explain why you assigned the variables in that way. 2. write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. show all your work, including the points used to determine the slope and how the equation was determined. 3. what does the slope of the line represent within the context of your graph? what does the y-intercept represent? 5. use the line of best fit to you to describe the data correlation.
